Abstract: The present disclosure discusses systems and methods for identifying biomarkers that can help with the diagnosis, prognosis, and treatment choices of patients with neurodegenerative diseases. Diffusion based magnetic resonance imaging can often fail for patients with a neurodegenerative disease because parameters fractional anisotropy, mean diffusivity, and radial diffusivity are based on simple models that can fail in the presence of neurodegeneration, such as demyelination. The present disclosure discusses systems and methods that enhance dMRI images and enable tractography to be performed on images of a damaged nervous system. The damaged tracks identified by the present system can be used as a biomarker for the assessment of patients. In some implementations, the biomarkers are converted into clinical scales that can be used to compare patients to one another or over time.

Abstract: In an RF spoiling method and apparatus for rapid spatial saturation in magnetic resonance imaging, a first RF pulse of a spatial saturation module is applied, and a first set of RF pulses of an imaging sequence is applied after the first RF pulse. A phase of an RF pulse, closest to the first RF pulse in the time dimension, in the first set of RF pulses is not coherent with a phase of the first RF pulse. This makes a phase cycle of the spatial saturation module and a phase cycle of the imaging sequence independent of each other, so the coherence of residual signals in the transverse plane can be destroyed more effectively, thereby reducing artefacts, and improving imaging quality.

Abstract: The present disclosure provides, in part, methods for high spatiotemporal resolution self-sorted 4D MRI. These methods can be used to improve resolution of abdominothoracic MRI during breathing by facilitating the sorting of information corresponding to individual MRI pulse sequences according to phase within the respiratory cycle.
